Human biofield and intention detection: individual differences.

OBJECTIVE: To evaluate a battery of biofield awareness tasks that address bioelectromagnetic and consciousness related mechanisms of action, and examine individual differences in integrative biofield awareness (IBA). METHODS: Six (6) biofield awareness tasks were designed: 2 involved the experimenter placing his or her hands near the subject, 2 involved intense staring with associated eye movements approximately 3' from the subject, and 2 involved gentle intention with virtually no movement. Each task required a binary response from the subject. There were 10 trials per task for a total of 60 trials; blocks of 6 trials contained one of each task. Subjects were 165 undergraduate psychology students at the University of Arizona Tucson, AZ. Subjects were also assessed on their awareness of their own biofields, and they filled out various questionnaires, including estimates of how well they thought they would do and their openness to spiritual beliefs and experiences. RESULTS: Percent IBA accuracy for the entire sample (n = 165) was 57.7 +/- 10.3% and was significantly above chance (50%) performance (t = 9.58, p < 0.0000001). Each of the 6 tasks was individually significant. Subjects significantly (t = -2.72; p < 0.007) underestimated their IBA performance below chance (mean, 46.1 +/- 18.4%). However, higher estimates predicted higher IBA (r = 0.26, n = 164, p < 0.0008). Measures of subjects' self-awareness of their own biofields, as well as belief in, and experience of, extrasensory perception (ESP) also predicted higher IBA. CONCLUSIONS: The findings support claims of energy healers that biofield awareness can be modulated both bioelectromagnetically (locally) and via conscious intent (distally), and that individual differences in biofield awareness are related to self-awareness and sensitivity to others.

Psychological, neuropsychological, and electrocortical effects of mixed mold exposure.

The authors assessed the psychological, neuropsychological, and electrocortical effects of human exposure to mixed colonies of toxigenic molds. Patients (N = 182) with confirmed mold-exposure history completed clinical interviews, a symptom checklist (SCL-90-R), limited neuropsychological testing, quantitative electroencephalogram (QEEG) with neurometric analysis, and measures of mold exposure. Patients reported high levels of physical, cognitive, and emotional symptoms. Ratings on the SCL-90-R were "moderate" to "severe," with a factor reflecting situational depression accounting for most of the variance. Most of the patients were found to suffer from acute stress, adjustment disorder, or post-traumatic stress. Differential diagnosis confirmed an etiology of a combination of external stressors, along with organic metabolically based dysregulation of emotions and decreased cognitive functioning as a result of toxic or metabolic encephalopathy. Measures of toxic mold exposure predicted QEEG measures and neuropsychological test performance. QEEG results included narrowed frequency bands and increased power in the alpha and theta bands in the frontal areas of the cortex. These findings indicated a hypoactivation of the frontal cortex, possibly due to brainstem involvement and insufficient excitatory input from the reticular activating system. Neuropsychological testing revealed impairments similar to mild traumatic brain injury. In comparison with premorbid estimates of intelligence, findings of impaired functioning on multiple cognitive tasks predominated. A dose-response relationship between measures of mold exposure and abnormal neuropsychological test results and QEEG measures suggested that toxic mold causes significant problems in exposed individuals. Study limitations included lack of a comparison group, patient selection bias, and incomplete data sets that did not allow for comparisons among variables.
